Description and Introduction

Dual 4-Input Positive-NAND Gates The SN74ALS20ADR is a dual 4-input positive-NAND gate manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** NAND Gate  
- **Number of Circuits:** 2  
- **Number of Inputs:** 4 per gate  
- **Output Type:** Push-Pull  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Propagation Delay (Max):** 11 ns at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-14  
- **Mounting Type:** Surface Mount  

### **Descriptions and Features:**  
- High-speed, low-power Schottky TTL logic  
- Dual 4-input NAND gates in a single package  
- Typical propagation delay of 8 ns  
- Low power consumption (typical ICC of 4 mA)  
- Fully compatible with most TTL families  
- Industrial temperature range support  

This device is commonly used in digital logic applications requiring multiple-input NAND functionality.

Application Scenarios & Design Considerations

Dual 4-Input Positive-NAND Gates

Alternative Part Number

  • 74ALS20AD --: Same 74ALS dual 4-input NAND logic function in SOIC-14 package, direct functional and pin-compatible replacement.
  • DM74ALS20AMX --: Dual 4-input NAND gate from the ALS family in SOIC-14, electrically equivalent with similar propagation delay and drive.
  • SN74ALS20AN --: Same TI ALS dual 4-input NAND die in a DIP-14 package, suitable when through-hole mounting is acceptable.
